PDF and DjVu

Special writing environments

Distraction-free writing

FocusWriter — Simple, distraction-free writing environment. It utilizes a hide-away interface that you access by moving your mouse to the edges of the screen, allowing the program to have a familiar look and feel to it while still getting out of the way so that you can immerse yourself in your work.

PyRoom — Fullscreen editor without buttons, widgets, formatting options, menus and with only the minimum of required dialog windows, it doesn't have any distractions and lets you focus on writing and only writing.
